摘要： In various embodiments of the invention, an interferometric display device is provided having an external film with a plurality of structures that reduce the field-of-view of the display. These structures may comprise, for example, baffles or non-imaging optical elements such as compound parabolic collectors. The baffles may comprise a plurality of vertically aligned surfaces arranged, e.g., in a grid. In certain preferred embodiments these baffles are opaque or reflective. These vertical surfaces, therefore, can substantially block light from exiting the interferometric display device in a substantially non-perpendicular direction. These vertical surfaces may, however, permit light directed in a substantially vertical direction to exit the display. The non-imaging optical elements, e.g., compound parabolic collectors, redirect light from large incident angles into more normal angles towards the display. As a result, the light reflected by the display to the user is also at a more normal angle.
